drugs.
Your judgement is impaired and could result in a dangerous situation that may cause
serious injury to yourself and others.
Safety Precautions
Before you turn on the power switch on the transmitter, always check to see that the
trigger is at the neutral position. Always turn the transmitter on first, then the receiver.
When you turn the system off, always turn the receiver off first then the transmitter.
This step is very important always follow this procedure.
If this procedure is not followed, injury to yourself and others as well as loss of control
could occur.
Adjustment Note
Make all adjustments to the radio control system with engine not running, or the electric motor disconnected.
If the engine is running or the motor is connected while adjustments are made the
model may run out of control.
Remove the main battery source from electric powered models when they are not
being used.
Should you accidently leave the receiver switch on the model could run out of control.
Caution
Do not touch
Do not touch the engine, motor, speed control or any part of the model that will generate heat while running.
Touching hot parts will result in serious burns.
Storage And Disposal Safety Precautions
Warning
(When using a Ni-cad battery to power your system)
At the end of a days operation store the system with Ni-cad battery discharged. Be
sure to recharge the system before it is used again.
You should fully discharge your systems batteries periodicity to prevent a condition
called "memory". For example if you only make two run in a day or you regularly use a
small amount of the batteries capacity, the memory effect can reduce the actual capacity even if the battery is charged for the recommended amount of time.
Prohibited
Do not throw a Ni-cad battery into a fire. Do not disassemble or attempt to repair a Nicad battery pack.
Overheating, damage and acid leakage may lead to burns, loss of eye sight as well as
numerous other types of injuries. The electrolyte in Ni-cad batteries is a strong alkali.
Should you get even the smallest amount of the electrolyte in your eyes, Do Not rub,
wash immediately with water, seek medical attention at once. The electrolyte can
cause blindness. If electrolyte comes in contact with your skin or clothes, wash with
water immediately.
Caution
Do not store your R/C system where it will be exposed to the following conditions.
• Extreme heat or coldness
• Exposed to direct sunlight
• Where humidity is high
• Where vibration is prevalent
• Where dust is prevalent
• Where there is steam and condensation
• Where the system would be exposed to engine exhaust
Storing your R/C system under adverse conditions could cause deformation and numerous other problems with operation.
(When using a Ni-cad battery to power your system)
Caution
When disposing Ni-cad batteries, cover any exposed contacts with some type of insulation to prevent short circuit.
Improper disposal could cause fire.
Safety Precautions
Prohibited
*Special Note!
Some states require special handling when Ni-cad batteries are disposed. Contact the State Agency responsible for recycling hazardous waste for the procedures in your state.

Use the R2-BSS-N battery holder to match your application.
If your model has a mechanical type speed control (Servo Driven for electric powered
models) inspect this component for a power supply regulator or voltage dropping Diode.
These device’s will cause a voltage drop to the receiver. Be sure to remove them prior
to installation in your model.
Assembly Precautions
Warning
Check
Check the receiver, servos, and battery connectors, to be sure they are firmly connected.
If a connector is not fully inserted, vibration may cause the connector to work loose
while the model is operating. This will result in loss of control.
Check
Operate each servo horn over its full stroke and check to see that the linkage does not
bind or is not too loose.
Excessive force applied to the servo horn by binding or poor installation may lead to
servo problems and cause result in loss of control.
Prohibited
The receiver antenna may seem long. Do not cut or alter from the original length.
If the receiver antenna length is altered, the receiver will be adversely effected. The
receiver will become considerably more susceptible to interference and high frequency noise which will result in loss of range and control.
Installation Note
Assembly / Adjustment
(Electric Car's and Boat's)
Isolate the receiver from vibration by attaching to the chassis or mounting plate with
thick double sided tape.
(Gas Powered Car's and Boat's)
Isolate the receiver from vibration by wrapping it in foam rubber or similar type cushioning material. Protect the unit from water damage by placing it in a plastic bag or
waterproof radio box.
The receiver contains precision electronic parts. These parts are vulnerable to vibration and shock. Any contact with moisture (water or condensation) may cause receiver
malfunction and loss of control.
Installation Note
Keep all devises that may omit high frequency noise, such as motor's, batteries, and
wiring that handle heavy current loads, at least 1/2 inch away from the receiver and
receiver antenna.
High frequency noise will cause a decrease in operating range and could cause loss of
control.
Use genuine Futaba parts only.
Use only genuine Futaba crystal set's as specified in this instruction manual.
The use of other than Futaba crystal set's will result in decrease of range as well as
loss of control. There are separate crystal's for the Transmitter and Receiver, there are
also crystal set's for AM, FM and Dual Conversion FM. Use only single conversion AM
crystal set's with this system.
Changing crystals in 72-75 MHz transmitter is illegal, however 27 MHz is allowable.
(For U.S.A.)
10
Install electronic speed control heat sinks as well as other components that conduct
electricity so they can not come in contact with aluminum, carbon fiber or other materials that conduct electricity.
If for example the speed control came loose while the model was running and touched
an aluminum chassis a short circuit may occur that would cause irreparable damage to
the system as well as loss of control.
Installation Note
Noise suppression capacitors should be installed on almost all motors.
If the proper capacitors are not installed, high frequency noise will reduce range and
cause loss of control along with various other problems.
Installation Note
Inspect all linkage installations and any point where metal could come in contact with
other metal parts. Make sure these parts do not touch other metal parts under vibration.
Should a linkage or other metal parts come in contact with other metal parts under
vibration the high frequency noise generated by this contact will cause interference
and possible loss of control.
Caution
Do Not disassemble any part of this system that is not specified in the instruction
manual.
Futaba will not be responsible for any damage due to improper disassembly of any
part of the radio control system.
